LOL okay I get the point... I'm not opposed to the Superman character being translated into an anime show. But let me ask you this: if Tony Stark had an anime show, and the way he suited up in that anime show, was him carrying around with him The individual pieces of his suit rather than using nanotech, do you think that would make any type of story wise sense?
I would say no, because nanotechnology for Iron Man works... Tony Stark is a genius, and he would use something like that to his advantage, And him using nanotechnology to suit up is also playing into his character: him being an engineering genius... Superman, on the other hand, has no need for nanotechnology. Nanotech wouldn't suit the Superman character because nanotech Is not an aspect that needs to be added, on the basis that, unlike Tony Stark, Superman can get away with wearing his costume underneath his clothes, performing the iconic shirt rip, and folding his clothes up real small and putting it in a small pocket that's on his cape (yes, that's a silver age reference)...
Honestly, it would be just as easy to have Superman have his suit and a duffel bag Rather than him perform the iconic shirt rip... I'm fine with the shirt grip combat I would also be fine with him carrying the suit on a duffel bag. While Superman is smart he is not a bonafide military genius. I like the interpretation that krypton became a xenophobic civilization that strayed away from interaction from the rest of the 28 known galaxies...
Having Superman wear nanotechnology makes absolutely no sense. Superman is super because of his abilities, not because his suit can magically form around him. Superman doesn't need nanotechnology to be super.
